The ionization (play) of crystals in a cabochon cannot be transmitted through a photograph, we can show in more detail on the video.

The mineral is valued for its great rarity, uniqueness, unusual inclusions - yellow, copper, golden, green, blue - iridescent iridescence, creating the effect of iridescence.

The only place on our planet where nuummite is mined is Greenland, the Nuuk region, to which nuummite owes its name.
Sometimes other dark stones with various inclusions are given out as nummites – for example, larvikites, etc.
Therefore, only Greenlandic nuumite can be a real nuumite, everything else is not nuumite.

To date, nuummite is very rare and popular in the market of stones.
The most popular Greenland's oldest stone, Nuummite or iridescent amphibolite, is most likely a trade name, not the name of the mineral.
